What are pregnancy tests?

A pregnancy test is a simple device used to detect the presence of human chorionic gonadotropin (hCG) in a woman's urine or blood. hCG is a hormone produced by the placenta during pregnancy. When a woman is pregnant, hCG levels in her body rise rapidly, and a pregnancy test can detect this increase.

Pregnancy tests are available in two main forms:

1. Home pregnancy tests: These tests are designed for home use and can be purchased over the counter at pharmacies and other retail stores. Home pregnancy tests typically involve collecting a urine sample and placing it on a test strip. If hCG is present in the urine, a color change or line will appear on the test strip, indicating a positive result.

2. Laboratory pregnancy tests: These tests are performed in a laboratory, usually by a doctor or healthcare professional. Laboratory pregnancy tests can detect lower levels of hCG than home pregnancy tests and can provide more accurate results, especially in early pregnancy. Laboratory pregnancy tests may involve collecting a urine or blood sample.

Pregnancy tests are generally accurate, but it's important to follow the instructions provided with the test carefully to ensure accurate results. If you receive a positive pregnancy test result, it's important to see a healthcare professional for confirmation and further prenatal care.
